7 Application filed April 29, 1921. Serial No. 465,457.

To all whom it may concern:

Be it known that I, Gnonon R. JoUoHINs, a citizen of the British Empire, residing in New York, State of New York, U. S. A., have invented a new and useful Improve ment in F reight-Car Roofs, of which the following is a specification.

The invention relates to metal car roofs, and more particularly to a corrugated metal carline and of an interlocking of the metal roof sheets with the carline and with each other, to form a flexible, weather-tight metal roof.

In order to make the invention more clearly understood there are shown, in the accompanying drawings, means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of example, have been delineated.

In the drawings Figure 1 is a side view of a part of a freight car, outlining the positions of the carlines and showing two forms of said carlines.

Fig. 2 is a transverse section of part of the roof, embodying the inventions as applied to a metal car roof.

Fig. 3 is a vertical cross section of the same on line AB of Figure 1 and of almost full size; and

Fig. 4, a similar View, comprising another shape of carline.

Referring to the drawings, 1 indicates the ridge pole; 2, the side wall plates; 3, S, the

carlines; 4:, the ridge cover, and 5 and 6, the" roof sheets.

In my invention, the roof sheets are provided with grooves or lips which embrace the edges of the carlines and interlock therewith and with each other in such a manner as to prevent an independent vertical movement of the sheets relative to the carline.

The carline is made with overhanging side edges and of a corrugated section, as shown in Figure 3 and is or may be of the same section and width throughout its length, except where attached to the roof frame in the usual manner of carlines.

Other sections of carlines, may, however, be used without departing from the merits of my invention. In Figs. 1 and 4 I illustrate flat-topped carlines 3, with which may be combined roof sheets 5, 6 having their side portions correspondingly shaped.

It is evident that the described lips or grooves may be formed integral with the plate, as shown at 7, or a separate edge-part 8 may be attached thereto by rivets, solder, welding, and the like, as in Fig. 4, so as to engage under the side edgeof the carline, without departing from the nature of my invention.

It will be understood that the metal roof sheets are horizontally flexible relative to the cal-lines to produce said flexible metal roof, and the arrangement of the side portions of the roof sheets are such as to make the roof weather-tight where the sheets are con- .nected together. It will be seen that my in vention is adapted for, and is shown in, a freight car roof, in which the metal roof sheets form the only sheathing elements.

What is claimed is 1. In a freight car roof in which metal roof sheets form the only sheathing elements, the combination with the carline, of metal roof sheets forming therewith a flexible water-tight metal roof, each roof sheet passing across and beyond a carline and having a portion engaging under the further side of the carline.

2. A freight. car roof frame in combination with side plates and purlins, carlines; integral metal roof sheets interlocked at their sides with each other and enveloping within the interlocking a portion of a horizontally disposed side flange upon the carline to form a weatherproof roof, with space between the sides and edges of the carlines and the roof sheets to provide desired horizontal flexibility.

3. In a freight car roof, in which metal roof sheets form the only sheathing elements, the combination with the side walls and carlines, of metal roof sheets forming therewith a flexible water-tight metal roof, the carlines having outwardly extending side flanges on their upper surface substantially on a plane parallel to the surface of the roof, a roof sheet shaped to extend forwardly beneath and thence upwardly and backwardly immediately beneath the lower surface of a side flange, then bent upwardly and forwardly around over the edge of the flange and to lie flat thereon, a contiguous roof sheet extending from the opposite direction over and beyond the upper surface of the carline and flange then bent downwardly and backwardly inclosing and interlocking the end of the sheet first mentioned and enveloping a portion of the carline flange within said interlocking, with spaces between the side and edges of the carline and the roof sheet to provide the desired flexibility.

4:. In a freight car root in combination With side plates and carlines, the combination of integral transverse root sheets, which at their sides interlock with each other formlng a weatherproof joint, said interlock inclosing an outward projection at the side of a carline thereby closely restricting vertical movement of the root sheets relative to the carlines, with side clearance between the roof sheets and the carlines to provide horizontal flexibility.

5. In a freight car root, the combination with side plates of metal carlines having witnesses.
